Application ned august 24.1907. seen No. scocca 'f 'To all whom it may concern: I

Be it known that I, GEOR'E R. MACOM- BER, a citizen of .the United Statesbresiding at New York city, in the countyy of New York and State of New York, have* invented certain new and useful Improvement in Vibratory Massage Apparatus; vand I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to `which it appertains to makeI and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference *marked thereon, which form a' 'moved farther from or nearer tothe axis of rotation to'regulate the strength of the vibratory movement.

The invention consists further in theprovision of -means in connection with the vibratory. massage ap aratus of takingup the vibration uponthe andle ofthe device.

. The'invention comprises various other de-i tails of construction and combinations and arrangements of parts which will be hereine after fully described and then specifically defined in the appended claimsf` My invention is illustrated in the accom# panying drawings, in which Figure '1` is' a perspective view of the ap paratus. Fig. 2 is a central longitudinal sectional view through the`device; Fig. 3 is a cross sectional view on line 3-3 ofFig. 2, and Fig. 4 is an enlarged detail view of two ofthe parts disassembled.

Reference now being had to the details of the drawings by letter, A designates a suitable casing in which the gear mechanism for driving the apparatu's is positioned and contains a shaft mounted 1n suitable bearings therein, and B is a suitable handle fixed to a projecting end of said shaft whereby the latter may be rotated. Y

C designates a gear wheel which is xed to the shaft B, the teeth of which Wheel are Patented Feb. 4,1998..

in meshwith thenteeth D upon the shaft D',

which-latter is j ournaled insult-able bearings within said casing. A beveled gearwheel E is fixed to the shaft'D and is in meshwith a bev.

eled gear Wheel E keyed or otherwise' securely 'fastened to theshaft G, whchisinountedin bearings in the tubular member H which is fastened to said casing. The shan-k portion of said casing, designated by letter K, is

tubular, as shown-clearly in Fig. 2 of theI drawings, and contains a collar I therein which is'held in place by means of a screw Iv j and 'about thecircumference of the said tubular shank portion are the .annular ribs J arranged in pairs and spaced apart, andfN designates rubber rings which are placed about the circumference of said hollow shank K and heldin place by being positioned intermediate said annular ribs. 'Asuitable handle Q lis provided which is chambered to receive the hollow shank portion of said casing, the outer circumference of the rings, preferably extending llaterally against the inner surface of the chamber of the handle and allow- Ving the handle to have a slight movement in;- dependent of said shank portionof the casing.'

designates-a coiled spring, the inner end oflwhich is fastened to the collar I in any suitable manner and its other end extending through said handle and en aged by means'of a -nut L. ,Said spring an rubber'rings, as shown, are provided for the purposeof taking up the vibration which wou d come upon the handle and which -is found in devices .of this n nature to be objectionable, as theoperator much ofthe vibrator-y effect of the'instru` ment as thearty being treated. Said tubular portion has its outer end flaring, asiat H', and 4R designates a saucer sha ed disk which telescopes over the circular flhnve H2 of said flaring end H'. f n will be noted that lsaid disk shaped member R has a lug R proecting from its circumference, the end of the ug having a flange R2 over which a cup shaped member T, of rubber or other material, may be fitted. It'will be' understood that various forms of contact massage 'cups may be adjusted to the headed lug R.

Mounted u on a squared ortion got the shaft G is a isk M having our radinlurms M projecting therefrom, each of said arms being threa( ed, and O-O designnteballs, each of which is mounted u on artlir'eaded arm M', and O designates ba ls which are of 490 y'holding the-"apparatus ordinarily gets/as smaller diameter than' theballs O and upon 81 ea'ch arm opposite an arm upon whic larger ball 1s mounted asmall'ball'O is held, as shown clearly in Fig. 3 of the drawings. The purpose lof having the balls of different sizes and mounted as shown and described thatin order that the Weight u on the axis of the' disk M may be thrown fart er from or nearer to the center Aof the disk in order to increase or decrease the vibratory movement. As said i balls have threaded aperturesit will be noted that they may be adjusteduponthearin'as ma be desired.

In order to hold the cup s aped disk R in place, a lug P projeets'from the outer surface thereof adjacent to its rim land engages a turning t i effect incident to the vibratorymovement bayonet slot h formed in the outer surface of the flange H2.- 1

In o eration, it will be noted that, by the multiplied gear', a very rapidrotary'movement ma kloe-imparted tothe shaft G by fie crank B .and by holding either the'convexed surface vof the disk R against any object to be massaged orthe cup 'l pro-l jecting from the edge of the disk, the desired ma be hadl and,`by the provision of the coi ed spring Vand ring upon the handle, the

Iiyibratory effect will not be imparted to the' operator holding the instrument. 3 n
